Trojan.fraud.pack infection and removal

Trying to remove this infection, at least thats what I think its called after scanning with Registry Mechanic Spyware doctor tool, which won't remove it unless you buy the product.

I have also tried Kaspersky Internet security v7 trial, Adware and CCleaner with no success. Does anyone known how I can remove this infection please.

the infection gives me a desktop picture "WARNING" spyware infection in the centre of the desktop. It also will not let me into the Task Manager and WinXP Home desktop scheme will not change back to anything like the fields for green grass etc.

It did remove 12 infections in my account & fixed the access problem to Task Manager and Desktop sestting but in the other User Accounts x3 in XP, things seem to still be wrong. Should I have started in Safe mode in XP and logged on as Administrator and run Malwarebytes in that account ?

I have found that my account in xp is cleaned but the other accounts seems to be still infected. Would running XP from Safe Mode - Administrator account be the correct way to shift this infection fully out of the system? Thanks
